Wiper blade packing case

Abstract

A wiper blade packing case including a plate-type lower panel; a plate-type upper panel; and a pair of covers, each of which has an elliptical cross-sectional surface corresponding to the cross-sectional surface of the receiving portion, and each of which is bent and extends from each of the shorter sides of the upper panel to close openings formed at both sides of the receiving portion.

The invention claimed is: 
     
       1. A wiper blade packing case used to pack a vehicle wiper blade, comprising:
 a plate shaped lower panel which has a pair of longer sides and a pair of shorter sides and is curved in a horizontal direction with respect to a longitudinal direction of a plate shaped surface; 
 a plate shaped upper panel which is bendable along a longitudinal side of one side of the upper panel and is curved in a horizontal direction with respect to a longitudinal direction of the plate shaped surface so that an accommodation part has an elliptical cross section shape for accommodating the wiper blade along with the lower panel, thus surrounding the plate shaped surface of one side of the lower panel; 
 a pair of covers which each have an elliptical cross section shape matching with a cross section shape of the accommodation part and each is bent and extended from each shorter side of the upper panel, thus covering open sides of two sides of the accommodation part; 
 a slot which is formed at one plate shaped surface of one of the pair of the covers; 
 an extension which forms an engaging protrusion passing through and being engaged to the slot and is extended from one side of the lower panel; and 
 a cut-off section of the extension at which the engaging protrusion is formed serves an engaging hole which allows the wiper blade packing case to be hung on. 
 
     
     
       2. A wiper blade packing case used to pack a vehicle wiper blade according to  claim 1 , wherein said engaging protrusion is cut off in part from the plate shaped surface of the extension and is overlapped with the plate shaped surface of the extension and is engaged with the slot. 
     
     
       3. A wiper blade packing case used to pack a vehicle wiper blade according to  claim 2 , further comprising:
 a rib which is bent from one side of the cover at which the slot is formed, and comes into close contact with the plate shaped surface of the extension. 
 
     
     
       4. A wiper blade packing case used to pack a vehicle wiper blade according to  claim 1 , further comprising:
 an assistant cover which has an elliptical cross section shape matching with the cross section shape of the accommodation part and is bent and extended from the lower panel and is overlapped with a corresponding one of the pair of covers and covers the open side of the other side of the accommodation part.
